COKE-FULLER.

SPECIFICATION forming part of Letters Patent No. 775,221, dated November15, 1904.

Application filed April 19, 1904. Serial No. 203,928. (No model.)

To all 10700712, 'l'fi Huey concern:

lVhen made hollow, the scraper-body may Beitknown that I, HARRYKING,acitizen of comprise longitudinal webs, as 151 and 152, a the UnitedStates of America, and a resident 1 bottom web 153, connecting the frontnds of 50 of "ashington, in the Distriet'of Columbia, 5 have inventedcertain new and useful Improvements in Coke-Pullers, of which thefollowing is a specification.

This invention relates to that class of cokepullers designed to beoperated by machine IQ for pulling coke from coke-ovens, which includesan under-working scraperoperative on the instroke to loosen the cakedcoke for withdrawal and a swinging coke-grasper adjustable into positionto grasp and hold the loosened coke over and above the scraper on theoutstroke.

The object of the invention is to provide simple means for operating theswinging plate.

Figure 10f the accompanyingdrawings rep- 0 resents a verticallongitudinal section of this coke-puller on line 1 1 of Fig. 2. Fig. 2represents a plan view thereof with a part broken out.

The same reference-numerals indicate corresponding parts in both thefigures.

This coke-puller is designed to be mounted on a suitable machinetraveling on a track located in front of the coke-ovens and preferablyoutside the track on which the cokere- 3 ceiving cars travel. Thismachine-car will carry suitable mechanism for thrusting the coke-pullerinto the oven and retracting it therefrom and for swinging it laterallyto gather the coke from opposite sides of the oven such. for instance,as that shown in United States Patent No. 731,911 to James EllwoodJones, dated June 23, 1903.

The coke puller comprises a coke loosening and discharging scraper 150,disposed at the 4 outer end of a shank-bar 140, which is reciprocatedand oscillated from the machine-car, as aforesaid. The body of thescraper is in the form of a wedge having a gradually-inclined or beveledfront face adapted to act as a coke-loosening surface on the instrokeand an abrupt rear face adapted to act as a coke scraping or pullingsurface on the outstroke.

said longitudinal webs, a bottom web 151, connecting the rear ends ofsaid bottom webs, and a back plate 155, constituting thescraper-surface. Puller-lugs, as 156 and 157, may be attached to thebottomas, for instance, to the bottom plate 153-to facilitate themovement of the coke-puller along the bottom of the coke-oven.

The coke-grasper is shown in this instance in the form of a swingingplate 160, hinged to the upper angle of the scraper 150 and extending ina transverse direction to the bar 1&0. The front edge 161 of this plateis preferably beveled to adapt it to the bottom of 4 the oven and ispreferably arc-shaped to conform to the curvature of the oven-wall. Arigid arm 162 is integral with or attached to the under side of theswinging plate near its rear edge and extends downward therefrom,preferably at right angles thereto and within the body of the scraper,and in the preferable construction two such arms are provided, in whichcase the arm 162 is located on one side of the center of the scraper andthe arm 163 on the other side. An actuating slidebar 170, also adaptedto be reeiprocated from the machine-car, has a pin-and-slot connectionwith the arm or arms 162 and 163 of the swinging plate 160, the slots,as 16 1, being preferably in the arms and the 8 pins, as 172, at theouter ends of a T-head 171 at the front end of said bar. This slidebar170 passes through a slot 158 in the back plate of the scraper andthrough a guideway 145, mounted on the bar 140. hen the 5 slide-bar 170is drawn backward, the swinging plate is closed over the front of thewedge-shaped body of the scraper and constitutes the activelifting-surface thereof, and when the bar is thrust forward said plate 9is swung into upright or approximately upright position, as shown inFig. 1, where it is adapted to grasp and hold the mass of coke above thescraper.

In the use of this invention when the oven is ready to be discharged thecoke-puller is thrust into the oven along the bottom thereof asufiicient distance to make a proper drawing of the coke. On thisinstroke the plate 160, constituting the beveled front face of thescraper, is in lowered position and operates as a wedge to lift the cokeunder which it passes and to loosen such coke from the caked mass ofcoke within the oven. As the scraper moves inward the main portion ofthe loosened coke falls behind the back plate 155, and at the inner endof the stroke a small portion is disposed directly over the front of thescraper. To secure the withdrawal of the latter portion, the rod 170 isthrust forward after the instroke of the coke-puller is completed, andthe plate 160 is thereby swung upward and held in open position, wherebythe coke immediately above the scraper is held during the outstroke andwithdrawn from the oven, together with the coke behind the scraper. Thisoperation of the coke-puller is especially advantageous when theinstroke terminates near the farther wall of the oven, as it cleans upand withdraws the coke adjacent thereto.

I claim as my invention 1. A coke-puller comprising an underworkingscraper adapted to operate on its instroke to loosen coke for withdrawaland on its outstroke to withdraw loosened coke, a swinging coke-grasperhinged to said scraper and provided with a rigid arm extending downwardwithin said scraper from the pivot of said cokegrasper, and a slide-rodhaving a pin-and-slot connection with said rigid arm for swinging itinto open and closed position.

2. Acoke-puller comprising an underworking scraper adapted to operate onits instroke to loosen coke for withdrawal and on its outstroke towithdraw loosened coke, a swinging coke-grasper hinged to said scraperand provided with a rigid arm extending downward within said scraperfrom the pivot of said grasper, and provided with a slot at its lowerend, and a sliderod provided with a pin adapted to engage the slot ofsaid arm for swinging said coke-grasper into open or closed position.
